5 Claims.. (01. 237-8) This is a division of my original applicationSerial No. 247,696 filed January 18, 1928, for Letters Patent of theUnited States for Improvement.

in methods of heating and ventilating.

,Structures hereinafter described including a.

radiator, a fan, and a motor therefor, in combination with a casing, arethe subject matter of my copending divisional application for LettersPatent of the United States for Improvement in heat exchange apparatus,Serial No. 412,972 filed December 10, 1929.

My invention relates to heating systemsinclu'ding a furnace comprising afuel burner in cooperative relation with a container in which anysuitable heating fluid, for instance, steam or water, may be heated; andconduits forming a circulatory system leading from and returning to saidcontainer and supplying said heating fluid to a radiator or radiators,to heat the atmosphere local to the radiator surface. The purpose andeffect of my invention are to facilitate and augment the transfer ofheat from the radiator surface to the adjacent atmosphere by more rapiddisplacement of the air at such surface than is possible by convection;and at a rate variable with the heat supplied.

As hereinafter described, my invention includes means for facilitatingand augmenting the transfer of heat from a fluid supplied to a radiatorto the atmosphere adjacent to the radiator, by utilizing power from theheating fluid to operate a motor to forcibly circulate the airrelatively to the radiator, by means of a rotary fan. 1

The typical heating system herein disclosed includes a gas burning waterheater ,and means for maintaining a forced circulation of water withinthe heating system, by an electrically controlled pump; the operation ofthe device being controlled by thermostatically operative means; andtheforced circulation of air thru the radiator is effected by a motorincluded in a bypass shortcircuiting the radiator with which it isassociated; so that theheating fluid is taken into the motor from thesupply conduit leading from the heater to the radiator, and the exhaustfrom the motor is discharged into the return pipe leading from theradiator back to the heater.

My invention herein claimed includes the various novel features ofconstruction and arrange-.

L a house heating system embodying my invention.

Fig. II is a'vertical sectional view of one of the radiator structuresshown the line II, II.

Fig. III is a plan sectional view of said structure, taken on the lineIII, III in Figs. I and II. Fig. IV is a fragmentary sectional view ofthe fluid motor indicated in Figs. I and II.

in Fig. 1, taken on Fig. V is a fragmentary sectional view of a modifiedform of fluid motor.

Referring to Fig. I; the house or other building comprising rooms orother inclosures 2. and 3, has, preferably in the cellar 4 thereof, theheater 6 inclosing the burners '7 and 8 supplied with gas from theconduit 9 under control of the thermostatically operative valve in thecasing 10. Said valve casing carries the tubular thermostatic element 11extending within the water conduit 12 which is connected with the pipe14 thru which hot water is-delivered from the cel-- lular heater units16 which are supplied with cold water thru the pipe 18. Said conduit 12is connected by pipes 20 with radiator units 21, from which the water isreturned thru pipes 23 to the pump 24 which is connected to said pipe 18and arranged to be operated by the electric motor 25, under control ofthe thermostatically operative switches 27. Said pump is operated tocirculate the water thru the system in the direction indicated by thearrows.

Referring to Figs. II, III and IV; each of said radiators 21 comprises acellular structure 30 which is a rectangular congeries of metal tubes 31having enlarged polygonal ends 32 which fit together and are sealed inconnection with a casing band 33 so as to form a cellular honeycomb ofthin metal walls and comprising separate pas sageways 35 for hot wateror steam and 36 for atmospheric air. Said radiator includes the inletport 38 and the outlet port 39 in communication with said passageways 35for the heating medium. The outer casing 40 for said congeries 31- formsa cold air inlet chamber 41 at the bottom thereof, an intermediatechamber 42 containing said cellular structure, and an upper outletchamber 43 for the heated air. The fluid motor 45 is preferably mountedin said inlet chamber 41 with a fan 46 arranged to force air into saidouter casing 40 thru the stationary louvers 47 in the lower portion ofsaid casing and thru the passageways 36 in said congeries of tubes, andout from the heated air chamber 43 into the surrounding atmosphere, thruthe foraminous panel'or grill 49.

Said fluid motor 45 includes an outer casing 50 provided with ports 51and 52 thru which the heating fluid in the system circulates from thepipes 20 to the pipes 23. Said casing 50 contains the rotor 54, theblade 55, and the shaft 56, which latter is journaled in said casing andin operative connection with said fan 46. Valves 57 and 58 may beprovided local to said motor casing to vary the relative volume of theheating fluid which shall be directed to the radiator 21 and thru themotor 45. It is to be understood that said valves may be adjusted tovariably determine the speed of rotation of the motor and consequent airdisplacement effect of said fan 46 to attain the desired efliciency oftransfer of heat from the radiator to the surrounding atmosphere; itbeing noted that such capacity should be increasedand diminished inaccordance with increase and decrease in the heat supplied to theradiator. Altho said fan 46 is indicated as in coaxial relation withsaid shaft 56, it is to be 'wheel 61 may be connected by a belt 62 witha pulley 63 on the shaft 65 which carries the fan 46. Said motor 59 maybe included in multiple relation with a radiator 21 in a bypass from thesupply pipe. 20 to the exhaust return pipe 23 and be controlled byvalves 57 and 58 as above described; but may be otherwise exhausted.

Therefore, I do not desire to limit myself to the precise details ofconstruction, arrangement,

or procedure herein set forth, as it is obvious that variousmodifications may be made therein without departing from the essentialfeatures of my invention, as defined in the appended claims.
